Final answer:
Eosinophils are derived from myeloid stem cells.
Step-by-step explanation:

Myeloid stem cells give rise to all the other formed elements, including the erythrocytes, megakaryocytes that produce platelets, and a myeloblast lineage that gives rise to monocytes and three forms of granular leukocytes, which include eosinophils. Therefore, the correct answer is option 2) CMP.
